On Wednesday, the U.S. Patent and Trademark Office canceled six trademarks belonging to the Washington Redskins after finding the name disparaged Native Americans.

But while the Redskins ownership continues to defend the legitimacy of its name and logo, other major American brands have backed away from offensive mascots like the Frito Bandito, a stereotypically Mexican, armed robber who hawked Fritos in the 1960s.

We've taken a look at some of the more offensive logos and mascots in history.

Aunt Jemima, 1889-Present

Company: Aunt Jemima/Quaker Oats

In the late 1800s, the Missouri newspaper editor Chris L. Rutt decided to name his brand of self-rising flour after "Aunt Jemima," a song performed by minstrel actors.

A former slave named Nancy Green was later hired to portray Aunt Jemima as a "mammy," a minstrel show caricature that female slaves as smiling, happy homemakers.

Chief Blackjack (1928-1987)

Organization: St. John's University

The Queens, New York-based college began calling its sports teams the Redmen in the early 1920s and adopted the Chief Blackjack mascot in 1928 when two students found a statue of him outside a cigar store.

The school used a variant of the wildly offensive logo you see here up until 1987, finally ditching the Redmen name in 1994 after pressure from Native American groups. The school's teams are now known as the Red Storm.

Darkie, 1933-1989

Company: Darkie Toothpaste

The name and mascot of Darkie Toothpaste, founded in Hong Kong in 1933, were also "inspired" by the minstrel show.

The brand quickly became popular in Asia, and in 1985, Colgate-Palmolive purchased a 50% stake for $50 million. Four years later, the conglomerate heeded the call of shareholders and activists and changed the name to Darlie, swapping the minstrel logo for one of a racially ambiguous man.
